Application of LoRa (Long Range Access) in Optimizing Internet of Things Using MQTT (Message Queuing Telemetry Transport) For Fish Feed Monitoring

Application of LoRa (Long Range Access) in optimization Internet Of Things Using MQTT (Message Queuing Telemetry Transport) For Fish Feed Monitoring: Data transmission is one of the technological advances that have begun to be developed to facilitate human work. Data transmission is widely known, such as sending messages from one point to another desired point to obtain and exchange information. Data transmission can work properly requires technology and tools that support the data transmission process. One of the technologies that support the data transmission process is WSN (Wireless Sensor Network), which is wirelessbased. The LoRa SX1278 module is one of the tools to support the data transmission process using frequencies from the LoRa module itself. The LoRa SX1278 module, as optimization of IoT (Internet of Things), uses MQTT (Message Queuing Telemetry Transport) because it has a wide range and can transmit data without an internet connection. In this study, 4 LoRa modules are used as a node/transmitter and 1 LoRa module as an access point/receiver. This data transmission uses a star topology, 4 nodes transmitting data to access points with different distances. Where the purpose of this study is to transmit data on the LoRa SX1278 module using a star topology and analyze the efficiency of data transmission distances and monitor the results of data transmission through IoT optimization using MQTT (Message Queuing Telemetry Transport), this research can be used as a data transmission learning module.
